<p>The device serves for placing snow posts or the like alongside roads. To make it possible for the device to be fitted in a simple manner, for example on the snowplough-holding plate of a lorry, to allow a relatively large number of snow posts to be carried on the device, to provide a surface on which an operator can stand and to make it possible, using a power-driven percussion device, to strike holes into the ground and also drive the individual snow posts into these holes once they have been made, the invention provides the following design features: a working platform (1) comprises a bearing surface which is delimited by vertical struts (11, 12, 13, 14) and, on one side, a height-adjustable supporting device. On the opposite side is mounted a rail (42) which can be displaced horizontally by means of a push-action cylinder (43) and on which is fixed a vertical guide rail (47). There are arranged on the guide rail (47), by means of a slide (49) which is driven by a push-action cylinder (55), a percussion hammer (50) provided with a boring or striking bit (58) and with a ramming device (60), and at least one post holder (72). <IMAGE></p> |
